Help For Arrow Keys

Hey,
I'm trying to build a Console RPG thats responds in realtime To The Arrow Keys the user enters.
This way I wont have to wait for the user to press "enter" in order to register an input. The problem is that the Arrow Keys do not have ASCII values, so how do I manage to go about and using them. I know they are supported through Unicode but I don't know how to use it with console programs. Thank You in Advance
